2016 Hyundai Tucson: multiple warning lights

Filed Jul 23, 2026 · Driver assistance, Electrical · WV

All the warning lights in the day lit up. Brake, LDWS, AEB, outside air temperature won’t read and the a/c blows hot. $486 to diagnose at dealer and they state that it’s an electrical issue due to a bad vacuum pump. I can’t get an answer as to whether the vacuum pump safety campaign was completed or not. Dealer wants $1500 to replace.

Took vehicle to dealership and had it diagnosed for the electrical system faults cause all the dashboard warning lights came on. Shop said it could be bad vacuum pump.

All dash warning lights are on and dash lights have a intermittent bright light surge. Hard to shut off engine and have to disconnect battery for electric power to shut off. Very noticeable hesitation in acceleration starting to drive

While driving, on multiple occasions all warning lights will come on and the car will start to lose power. The headlights constantly go off and come back on randomly. Turn the blinker on and the rear window wipers intermittently come on. The vehicle has been towed to the dealership so many times and we either get “can’t duplicate” or needs oil change, which had just been done. Now we are being told that we need a second engine replacement. Unfortunately this time it will not be covered by warranty. We have reached out to Hyundaii Motors 3 times and the BBB Auto but they stand behind it not qualifying for the Lemon Law. Hyundai should have some obligation as all these issues are “known issues” just not recalls.The 2016 Hyundai Tucson is not a safe vehicle.

Three weeks ago my dash board lit up like an orange Christmas Tree, with "ABS failure" warnings. I found the Hyundai recall notice in our car file. It said that when the dash warnings appeared, the danger of an engine fire was imminent and that should contact the Dealer that I bought the car from (Hyundai Motors- Naples, Florida-USA). I did so. personally. An appt. was scheduled. This morning (Fri. 11/15/24)upon arrival, a pleasant young woman informed me that Hyundai sent out lots of notices like this, but they didn't apply to my vehicle. I showed her the recall notice with my car's Vin number printed on it. She went back to her boss who told her "We fixed that for him three years ago," Now, I am not certain of anything, but I NEVER brought the car in for an ABS system fix three years ago. I didn't know that I even had an "ABS" system until three weeks back, when the dash board lit up. Politely, I asked the young woman to bring my car back out, as we were done. She offered to make another appointment to "look" at the dash indicators." I said" No, we are done." So, now what do I do? Is the car safe to drive or not? I own and operate an older Hyundai Santa Fe as well. I would be appreciative of your advice. Thank you in advance for your cooperation. The Tucson is a good car. I just don't want it to blow up on me. [XXX] , Florida-USA INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

When both driving and idling, the car will either stall or feel like it is about to stall, when all of a sudden the vehicle “pauses” for a second and then all of the dashboard lights come on. This has now happened at least 4 times in the past month. It will reset after turning the car off, but on more than one occasion after turning the car off, the engine doesn’t restart right away. Thankfully, the car has restarted and it resets the dashboard lights. My safety is a concern if my car stalls while driving at any speed! I have yet to take it to the dealer, as there’s a VERY long wait for an appointment - another recurring issue. No one has inspected this for me, and it is very concerning. There is plenty of evidence that this is happening to others in both online forums and Hyundai owners sites online.

1. January 7, 2022 my vehicle began to lose engine power, as I began to try and find a place to pull over safely, the car stalled. It would not immediately start again for several hours. It had to be pushed out of the way. The engine failed due to wear of connecting rod bearings with no previous indication of engine issues. 2. Due to the sudden stall and having to push the vehicle to a safe location, myself and passengers could have easily been hit by another vehicle. 3. A dealership has confirmed the failed rod bearings. 4. The vehicle's engine has been inspected and photos taken by the dealership and submitted to Hyundai corporate. 5. It was not until the car stalled that the oil light illuminated. When I started the car back up several hours later, all lights were gone and no error codes were present. There was no previous warning lights before this incident.

I'm mid may-end of may I took it in to Fort mill Hyundai the first time because it was starting to crank hard, sounded funny and my dashboard lights would come on saying I needed oil and there was an engine issue. When I idled too long the car would just die, I'd have to shift into park actually turn the car off and let it sit 1-3 mins turn it back on and all the lights would be off and it would drive like it did before it died, loud. They did testing on it and said these repairs (crankshaft sensor, spark plugs and I think an oil change) should fix it. This was less than a month after my previous oil change. Got the car back 3-4 days later and it sounded better but I still felt like it didn't drive and smooth as it should. 2-3 weeks goes by and my oil light again comes on only with sharp turns. The car over the next couple of days would do the loud cranking noise, didn't drive well over 60 and the engine light came on and gauges would go down but would be fine again once the car was turned off for a couple min like 5 . I set up an appt to hVe them look it over again because of the lights coming back on. Not even 2 days later twice going to and from work it completely died out on me (like the first time) but this time it would turn over once it was out in park and turned off correctly. First time I was in the middle of traffic at a red light waited 10 mins multiple times trying to turn the car on to move to the side and it wouldn't. I let it sit for 5 mins without trying to turn it on and it started the gauges didn't work and it was VERY loud stuck in like first gear wouldn't go above 20 mph. Pulled into a neighborhood turned it off to let it cool off again thinking it was over heating. It would crank but again lights still all on and the gear gauge didn't work (down at 0 liek the car was off). I waiting like 20 mins it still had the lights on but the gauges worked, when I tried to drive home it wouldn't go about 45mph or out of 2nd gear.

Originally when I purchased my car I complained to the dealer about my radio going black and they claimed it was due to the cold and brushed it off. Now recently I had the same issue but now as I was driving straight on the highway all of the lights on the dash keep flickering on and off telling me to check every system. My car signals/hazards will not work. Speedometer will not work along with blind spot recognition and other things.

I was driving my vehicle down my street when the engine died. Right before it died, I heard a brushing noise and then all the lights illuminated on the dash. There were no other warning noises or lights prior to engine failure. I checked the oil dipstick and there was no oil registering on it. The smear that was on the stick was black. The check engine or low oil light never came on to warn me of a potential problem. There is also no oil on my driveway which would indicate a slow leak. It was towed to the dealer where they told my the engine was dead and I needed a new one. This is not covered under the 10yr./100,000 mile powertrain warranty since I bought this (a year ago) from a friend who was the original owner. It has approximately 89,000 miles on it now. I'm thankful I was in my neighborhood when the engine failed and not on the interstate where I had been moments prior to this incident. It is still at the dealership where I have been quoted $7-9k for an engine replacement. They have offered $2,800 for a trade-in towards another vehicle as an option.
